The host OS interface name and VPP identifiers contain the same information
represented in different ways. They both reference the PCI bus number, slot
number, and function number. The Interface name contains the values in decimal
while the identifier shown in VPP uses hexadecimal.

Using this pattern, make a note of the VPP identifiers for the next step. In
this example, since enp0s20f1 and enp0s20f2 are the interfaces to use,
the corresponding VPP IDs are 0000:00:14.1 and 0000:00:14.2.

If the interfaces do not appear in the showinterface output, the default
driver did not attach to those interfaces and they may require a different
driver instead. To see a list of available drivers, use the following command
from config mode:
